i think the setup with an 8" SCT (with a reducer) is pretty common among EAA users (I use an Evo 8" + 0.63 reducer + ASI 294MC Pro myself). What would be an upgrade worth doing (i.e. worth saving for and more than "a tad better" ? I'm asking in the context of observing smaller objects (like galaxies) not nebulas.
- a Hyperstar is one option, but because of the wider field, I think it's more appropriate for larger objects like nebulas.Same with a RASA 8".
- a 9.25" SCT will of course bring more light (approx 1.33x if only judging by the radius) but I'm not convinced it justifies selling the existing one and buying the new OTA + mount.
- a 11" SCT will bring ~ 1.9x more light and more angular resolution. The downside is longer cooling. I'm not looking at an 11" RASA unless I win at a lottery :-)
Any other possibilities?
